Method Details

asElementType

protected final ATNConfig asElementType(Object o)

Description copied from class: Array2DHashSet

Return o as an instance of the element type T. If o is non-null but known to not be an instance of T, this method returns null. The base implementation does not perform any type checks; override this method to provide strong type checks for the Array2DHashSet.contains(Object) and Array2DHashSet.remove(Object) methods to ensure the arguments to the EqualityComparator for the set always have the expected types.

Overrides:

asElementType in class Array2DHashSet<ATNConfig>

Parameters:

o - the object to try and cast to the element type of the set

Returns:

o if it could be an instance of T, otherwise null.

createBuckets

protected final ATNConfig[][] createBuckets(int capacity)

Description copied from class: Array2DHashSet

Return an array of T[] with length capacity.

Overrides:

createBuckets in class Array2DHashSet<ATNConfig>

Parameters:

capacity - the length of the array to return

Returns:

the newly constructed array

createBucket

protected final ATNConfig[] createBucket(int capacity)

Description copied from class: Array2DHashSet

Return an array of T with length capacity.

Overrides:

createBucket in class Array2DHashSet<ATNConfig>

Parameters:

capacity - the length of the array to return

Returns:

the newly constructed array
